History It was found in the dry bed of river Hekandue, a left tributary of river Jasačnaja in the Magadan district, Russia. The main mass of 272.3 kg was found in June 1967 by the geologist F. A. Mednikov during a survey. The mass was a triangual shaped thumbprinted meteorite lying among the stones of the brook bed. A second specimen of 51 kg was found in October 1967 at a distance of 20 m from the first one by I. H. Markov with a mine detector 1967. The main mass was turned in to the Academy of Sciences of the USSR. During a new expedition in 2004, Dmitri Kachalin recovered about 50 kg of new material. Remarkably, many of the new specimens (about 20%) were found to contain olivine crystals and so revealed the silicated nature of the meteorite. The pallasitic structure was not discovered previously during studies on small metal-only sections of the original mass. Composition and classification Seymchan belongs to Main Group pallasites, but it is considered anomalous due to its high Ir content. Before the discover of its pallasitic structure it had been classified as IIE anmalous coarse octahedrite. Seymchan is considered a stable and rust-resistant pallasite. Specimens Due the heterogeneous structure of Seymchan, there are two types of specimens: with or without olivine crystals. It is worthy to note that the specimen pictured to the right shows an interesting, seldom seen feature of iron meteorites. The widmanstatten pattern on the left hand side of the specimen can be seen to bent. This is caused by the sheering of the meteorite as it broke up during atmospheric reentry and serves as testimony of the violent experience a meteor is subject to as it falls through the atmosphere.
